nc: Add number censored.

Description

Add number censored.

Usage

nc(x, ...)
## S3 method for class 'ten':
nc(x, ...)
## S3 method for class 'stratTen':
nc(x, ...)

Arguments

x

An object of class ten or stratTen.

...

Additional arguments (not implemented).

Value

• The original object, with new column(s) added indicating the number censored at each time point, depending on attr(x, "shape"):
• "long"
  the new column, c, gives the number censored at each timepoint, by covariate group.
• "wide"
  new columns, beginning with c_, give the number censored at each timepoint, by covariate group. There is an additional nc column giving the total number censored at each timepoint.
• A stratTen object has each ten element in the list modified as above.

Examples

data("kidney", package="KMsurv")
t1 <- ten(survfit(Surv(time, delta) ~ type, data=kidney))
nc(t1)
nc(asWide(t1))
## stratified model
data("pbc", package="survival")
t1 <- ten(coxph(Surv(time, status==2) ~ log(bili) + age + strata(edema), data=pbc))
nc(t1)
